JL Audio M6 Series 10" Subwoofer

M6 10-inch Marine Subwoofer with/without Transflective™ LED Lighting for Infinite-Baffle Use (250 W, 4 Ω) - Gloss White Trim Ring, Gloss White Sport Grille

With appropriate system setup, the addition of a subwoofer allows your smaller main speakers to be free of the burden of reproducing low frequencies. This allows your whole system to play louder and to sound cleaner at all listening levels.

Purpose-engineered and built for real marine duty, the M6 infinite-baffle woofers are designed to operate without a dedicated enclosure. Long excursion capability and rugged suspension systems help produce deep, powerful bass response that will transform your boat's audio system.

The M6-10IB is best used with amplifier power in the 75W - 250W range and is optimized to operate with a large volume of air behind it (at least 2 cu. ft. / 56.6 l). If you need a Subwoofer that operates in a small sealed enclosure, select our M6-10W, instead.

Like all JL Audio marine speakers, this driver is built to withstand a real saltwater marine environment and deliver years of listening enjoyment.

Summary:
The design of marine products requires extensive materials testing to achieve reliability and longevity.

Detailed Information:
Building serious marine products requires a real commitment to environmental testing and materials specification. To this end, JL Audio has invested in Ultraviolet testing chambers (to simulate years of sun exposure) and Salt Fog chambers (to simulate years of exposure to salt-water environments). This testing is critical to building products that will not only sound great in your boat, but will also sound great for many years.

Materials Used:

• injection-molded mica-filled polypropylene cone bodies with synthetic rubber surrounds, specifically formulated with UV inhibitors for marine duty.
• Marine-grade, synthetic fiber spiders with progressive roll designs to withstand high humidity.
• Specifically engineered polymer baskets are corrosion and UV-resistant and encapsulate the woofer's motor system to prevent corrosion.
• Gold-plated, marine-grade brass connection terminals
• Marine-grade stainless steel mounting hardware is included.

Built in U.S.A. with Global Components

Summary:
JL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.

Detailed Information:
At a time when most audio products are built overseas, JL Audio’s commitment to in-house loudspeaker production continues to grow. To pull this off in a competitive world market, our production engineering team has created one of the world’s most advanced loudspeaker assembly facilities and established a global network of quality component suppliers who build to our specifications. This, combined with our commitment to state-of-the-art assembly technology, allows our skilled workforce to efficiently build JL Audio products to extremely high quality standards, right here in the U.S.A.

Since most of our premium loudspeakers incorporate proprietary, patented technologies requiring specific assembly techniques, we find it is vital that the people who designed them have close access to the people manufacturing them. The following JL Audio products are built in our Miramar, Florida factory, with global components:

• Subwoofers: W7, W6v3, TW5v2, TW3, TW1, W3v3
  
• Enclosed Car Subwoofers: Stealthbox®, PowerWedge™, ProWedge™, H.O. Wedge™ & MicroSub™ Enclosed Subwoofers
• Marine Loudspeakers, Marine Subwoofers and Marine Enclosed Loudspeakers
• Home Subwoofers: Dominion™, E-Sub, Fathom® and Gotham®

Enclosure Notes
* The enclosure recommendations listed above are external dimensions which assume the use of 0.75 in (19 mm) thick material. If you are using 0.625 in (16 mm) thick material, subtract 0.25 in (6.5 mm) from each dimension. Do not use any material with a thickness of less than 0.625 in (16 mm) as this may compromise the rigidity of the enclosure.
* All enclosure volumes listed above are net internal volumes! Driver displacement, port displacement and brace displacement must be added to obtain the final gross internal volume. All enclosure dimensions above have already taken this into account.
* When using multiple subwoofers in a common enclosure you will need to recalculate the enclosure and port dimensions. For assistance please contact your authorized JL Audio dealer or JL Audio Technical Support.
* We recommend the use of this speaker in a bi-amplified system using high-quality satellite speakers and a high-quality amplifier. We do not recommend the use of this subwoofer with a passive crossover (coil), as this type of device will adversely affect performance.
* All specifications are subject to change without notice.

Safety Notice
Prolonged exposure to sound pressure levels in excess of 100dB can cause permanent hearing loss. This high-performance speaker can exceed this level. Please exercise restraint in its operation in order to preserve your ability to enjoy its fidelity.

When installing a subwoofer in your vehicle, it is extremely important to secure the enclosure firmly. We recommend bolting the enclosure through the metal of the floorpan or the frame of the vehicle with large diameter washers for reinforcement. If an enclosure is not firmly attached, it can become a projectile in a collision. This is particularly important in a hatchback, station wagon, sports utility vehicle, or van.
